LAST-BLOCK FASTENER- Specification of Letters Patent.

Application filed March 17, 1906. .Serial No. 306.605-

improved means for adjustably securing the instep-piece to the body of alastblock, it being further desired to utilize the flexible cord foroperating the fastening means to connect the instep-piece and said bodyfor the purposedof preventing them from becoming separate These objectsI secure as hereinafter set forth, reference being had to theaccompanying drawings, in which Figure 1 is a perspective view of alastblock, showing my invention as applied thereto. Fig. 2 is a verticalsection of the last-block shown in Fig. 1, illustrating my invention indetail; and Fig. 3 is an inverted plan of the insteppiece, furtherillustrating one of the detail features of my invention.

One frequent source of annoyance when Working with last-blocks ashitherto known to the art has been due to the fact tllli the variousmeans for detachably securing the instep-piece to the body of the blockhave been of such a nature that considerable time was necessarilyexpended in detaching said pieces, and, further, when a number oflastblock bodies and'instep-pieces were thrown together after use theparts constituting a complete last-block became separated, not onlyrequiring considerable trouble and time in order to properly assemblethe various sets, but also frequently resulting in the loss of therelatively small instep-pieces. By my invention I overcome these variousobjectionable features, since I provide means whereby the catch forholding the insteppiece and the last-block body together may beinstantly operated to separate said parts, and Iso arrange thisoperating means that it is a practicable impossibility for theinsteppiece and the last-block body to become separated.

Referring to the above drawings, A represents a last-block body havingan insteppiece B fitted to it. This piece is detachably secured inposition, partlybymeans of a doWer pin a, which fits into a suitablerecess in the or recess a, formed partly in the last-block bod A andpartly in the instep-piece B.

Sai bolt or catch normally extends partly in the portion a and partly inthe portion b of the'above-mentioned recess, and I connect Patented Oct.30, 19cc.

instep-piece, and artly by means of a slid I ing bolt or catch whichoperates in a hole it to the instep-piece A by means of a'spring- Wire 6which passes through it and is provided at its opposite end with an eyefor the reception of a screw or tack b. The bolt or catch b is madetubular for the reception of a flexible connecting-cord b, which ma beof.

any suitable material and held to said olt by means of the spring-wire 6which passes through one end of it. The opposite end of said cord isfastened in any suitable manner to the last-block bod A, in-the presentinstance by being tightl y held in a hole in said body by means of awedge (L The insteppiece B. is recessed to permit of the movement of thespring-wire b away from the ad-.

j acent surface of said ieceas, for example, when the bolt 1) is pulledinto the portion b of the hole or recess by means of the cord b thenormal position of the spring-wire being preferably that illustrated.

It will be seen that the bolt 12 and the pin a are so placed relativelyto each other that the instep-piece B is tightly and firml held inposition when once it has been place upon the last-block body by firstentering the dowel-pin a into the recess of said piece, while permittingthe bolt to be first moved into the portion 1) of its recess andafterward to spring out of said recess into the part a thereof when saidtwo parts have been brought in line. I I

No ordinary force applied to the insteppiece is suflicient to detach itfrom the lastblock body, though if it be desired that these pieces betaken apart-as, for example, in order to Withdraw the structure from ashoe an outward pull upon the cord b draws the bolt 1) into the portion5 of its recess and then results in the separation of said parts.

Owing to the fact that the ends of the cord 6 are respectively attachedto the two pieces A and B constituting the last-block body, these lattercannot be separated or mixed with the similar parts of otherlast-blocks.

I claim 1. The combination of a last-block body,

an instep-piece, means for connecting said parts including aspring-actuated bolt carried by one of the parts, a cord having one endconnected to one part of the last-bock, and a spring-piece engaging thecord and arranged to fasten it to said sliding bolt so as .to preventthe permanent separation of said parts, substantially as described.

2. A last-book consisting of a body portion, an instep-piece, a pincarried by one of said parts fitting in a recess in the other part, atubular bolt carried by one of the parts and entering a suitable recessin the other, said bolt and pin being placed to tightly hold togethersaid two parts, a spring attached to one of the parts and entering thetubular bolt, and a cord extending into the bolt and held therein bysaid spring, substantially as described.

3. A last-block consisting of a body por- 20 tion, an instep-piece, apin on one of the parts fitting in a recess in the other part, a secondrecess formed partly in one piece and partly in the other, a tubularbolt movable in said second recess, a spring-Wire attached to one of theparts of the block, and a cord connected to the other part, said cordextending through the second recess and into the tubular bolt and thespring extending into the bolt so as to engage and retain the spring inposition therein, substantially as described. In testimony whereof Ihave signed my name to this specification in the presence oi tWosubscribing Witnesses.
